LEWIS HAMILTON has warned rival Fernando Alonso the gloves are off as he bids to rescue his fading world title hopes in Sunday’s Suzuka showdown.

The 27-year-old, who announced last week he will be quitting McLaren for rival Mercedes at the end of the season, is so far behind in the points table that nothing but victory in the Japanese Grand Prix will do.

So he is pinning his hopes on a plan of all-out attack as he takes the fight to his former team-mate and bitter rival, who leads the world championship for Ferrari.

Hamilton said: “In terms of the championship there’s nothing to be gained by analysing the points table.

“From now it’s simply gloves off. As in Singapore I’ll come out fighting. I’ll just be hoping for a better result this time.”

Hamilton heads for the Far East after the bitter blow of retiring while leading the last round in Singapore.

Victory in the night street race would have dramatically altered the world title fight and put Hamilton almost within striking distance of the Spaniard.

Instead he has slipped from second to fourth in the championship, a huge 52 points behind Alonso with six rounds remaining.

Hamilton had been roaring away to his third victory in four races when his gearbox failed in Singapore.

It was a big disappointment after his heroic battle to roar back into title contention over the previous four races.

Five days later, Hamilton amazed the Formula One world by announcing he is quitting the team that has been his home for more than half his life to join Mercedes. There was more bad news for McLaren as Jenson Button looks to assume the mantle of team leader at one of his favourite race tracks.

The 32-year-old was hoping to return in style to the scene of the dramatic victory in his 200th Grand Prix 12 months ago.

Instead the team revealed he nurtured his car to the finish line in Singapore only for his engineers to discover his Mercedes gearbox had suffered the same terminal fate as Hamilton’s.

And changing it means his glory bid will have to start from five places further down the grid after the penalty for changing the gearbox is applied.

Like Hamilton, but even further adrift 75 points down on Alonso, the penalty may be the killer blow to Button’s hopes this year.
